Modern Apple devices are renowned for their ability to remember user preferences, including wireless networks. Automatic connection Connecting to a known Wi-Fi network significantly speeds up performance, but sometimes this feature can become a nuisance. For example, a laptop might stubbornly lock onto a weak neighbor's signal or try to connect to a network whose password has long since been changed.
In such situations, you need to forcefully delete the connection profile from the system memory. This action will cause your MacBook Air The network will no longer be recognized as familiar and will require a new password each time you try to access it. This process is simple, but it has its own nuances depending on the operating system version installed on your device.
In this article, we'll cover all the methods for deleting networks in detail, from default settings to a full configuration reset. You'll learn not only how to forget unnecessary connections but also how to manage network priorities so your laptop always selects the fastest and most reliable internet connection.
Why isn't my MacBook Air connecting to WiFi properly?
Users often encounter a paradoxical situation: the network seems familiar, but the connection fails. Cached data Old passwords or changed router security settings can create conflicts. The system attempts to use saved encryption keys that are no longer relevant for the access point.
Another common cause is confusion between networks with the same name (SSID). If you've moved or changed providers but left the router name the same, your MacBook may attempt to apply old security settings to new hardware. This results in endless, unsuccessful authorization attempts.
⚠️ Important: Before deleting a network, make sure you have the current password handy. After performing the "forget network" procedure, your device will completely erase all data about this connection.
It's also worth considering that some corporate or educational networks require periodic certificate renewals. If a certificate has expired, a simple reboot won't suffice. In this case, deleting the network profile is the only surefire way to force the system to prompt for new credentials again.
Deleting a network in macOS Ventura and later
With the release of the operating system macOS Ventura Apple has completely redesigned the System Preferences interface, making it similar to the menus on iPhone and iPad. Wi-Fi network management is now more intuitive, but the button layout has changed. To delete a network, open the Apple menu in the upper left corner of the screen and select System Preferences.
In the window that opens, find the section Wi-Fi in the sidebar. If you're not in the main Wi-Fi menu, click "More" or "Advanced" next to the wireless network switch. This is where you'll find a list of all known access points on your laptop.
☑️ Check before deletion
In the list of known networks, find the one you want to delete. To the right of the network name, you'll see an icon with three dots or an ellipsis button. Clicking it will display a context menu where you can select an option. Forget this networkThe system will immediately delete the saved password and security settings for this SSID.
If you want to remove multiple networks at once, in newer versions of macOS you can do so by selecting them and using the corresponding button at the bottom of the list. However, most often, you need to selectively remove a specific problematic connection. After doing this, your laptop will no longer automatically connect to that access point, even if it's within range.
Instructions for macOS Monterey, Big Sur, and earlier versions
In older versions of the operating system, such as Monterey, Big Sur or Catalina, the System Preferences interface looks different. There's no sidebar with icons, and all controls are concentrated in the classic windows. To start the process, go to the Apple menu and select System Preferences, and then find the icon Wi-Fi.
Unlike the new versions, here you need to click a button Additionally, which is usually located in the lower-right corner of the window. A new dialog box will open with a list of all preferred networks. This list is sorted by priority: the higher the network, the more likely your MacBook will try to connect to it.
Find the network you don't need in the list and click to select it. You'll see a minus sign below the list. (-)Clicking this button will delete the selected profile. It is important to click the button. OK or Apply in the lower right corner to save your changes. Without this step, all changes will be temporary and will be reset once the window is closed.
| macOS version | Path to settings | Action |
|---|---|---|
| macOS Ventura+ | System Preferences -> Wi-Fi -> More Details | Click on the three dots -> Forget |
| macOS Monterey | System Preferences -> Wi-Fi -> Advanced | Select network -> Button (-) |
| macOS Big Sur | System Preferences -> Wi-Fi -> Advanced | Select network -> Button (-) |
| macOS Catalina | System Preferences -> Network -> Wi-Fi -> Advanced | Select network -> Button (-) |
It's worth noting that in very old versions of macOS, the path may lie through the panel. Net, where you need to select the Wi-Fi adapter on the left, click Additionally and manage the list from there. The principle remains the same: find, select, delete, and save.
What to do if the network list is empty?
If the desired network name isn't in the list of preferred networks, it's possible that your laptop has never successfully connected to it, or the profile is corrupted and hidden by the system. In this case, a full reset of the network modules will help.
Radical Method: Resetting Network Settings via Terminal
Sometimes the graphical interface crashes, and deleting a network using the usual method fails. In such cases, Terminal — a powerful command-line tool for macOS. This method allows you to forcefully delete configuration files for wireless connections.
To begin, open Terminal. This can be done through Spotlight search (by clicking Command + Space and entering "Terminal") or finding the program in the folder Programs -> UtilitiesYou will need to enter commands to delete files that store information about preferred networks.
sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plistAfter entering this command, the system will ask you to enter the administrator password. As you enter the password, no characters will be displayed on the screen—this is a normal security measure. After entering, press EnterThis command will delete the file that contains a list of all known Wi-Fi networks and their passwords.
⚠️ Note: This method will delete ALL saved Wi-Fi networks at once. You'll have to re-enter passwords for all home, work, and public networks you use.
After running the command, you must restart your computer. When you restart, macOS will create a new preferences file with factory settings. MacBook Air It will behave as if it just came out of the box in terms of wireless connections. This is guaranteed to solve software issues with the Wi-Fi module.
Manage network priorities and automatic connections
You don't always need to forget a network. Sometimes, changing the priority order is enough. macOS is designed to always try to connect to the network that's higher in the priority list. If you have two routers at home with the same name but different speeds, you can force your laptop to ignore the slower one by simply moving it down in the list.
In older versions of macOS (before Ventura) in the window Additionally You could drag and drop networks to change their order. In newer versions, this functionality is hidden, and priority is determined by connection history and signal strength, but deleting unnecessary networks remains the primary management tool.
There's also an automatic connection feature. If you want your laptop to stop automatically accessing public hotspots in cafes, simply delete those networks after use. Automation The connection process is good for home use, but dangerous in public places with open access.
- 📶 Deleting a network resets all security settings for a specific SSID.
- 🔒 When you reconnect, the system will ask for the password again, even if you remember it.
- 🔄 Changing network priority helps avoid connections to weak signals.
It's important to understand the difference between "disconnecting" and "forgetting" a network. Disconnecting simply terminates the current connection, but the MacBook will attempt to connect again after a few minutes. Forgetting a network permanently removes it from memory until you choose to connect again.
Troubleshooting if the network is not deleted
There are situations when a network "sticks" and won't be deleted either through settings or the Terminal. This is often due to active background iCloud sync processes. Wi-Fi network keys can be synced between your Apple devices. If you deleted a network on your MacBook but it immediately reappears, check your iCloud Keychain settings.
Disable key synchronization while deleting the network. To do this, go to System Preferences -> Username (Apple ID) -> iCloud and find the item Bunch of keysAfter disabling, try deleting the network again. This will break the cycle of constantly overwriting settings from Apple servers.
Why does the network come back after being deleted?
This most often occurs due to iCloud Keychain syncing. If this network is saved on your iPhone or iPad, it will automatically reappear on your Mac. Delete the network on all devices at once.
Another possible cause is corporate configuration profiles (MDM). If the laptop belongs to an organization, the administrator may have blocked the ability to change network settings. In this case, you'll see a message stating that your organization manages the settings.
If all else fails, try creating a new user on your MacBook. Log in with the new account and test your Wi-Fi connection. If everything works fine, the problem lies with corrupted preferences files for your primary user, which you'll need to clean manually by searching for hidden files in your library.
Frequently Asked Questions (FAQ)
Will this remove the Wi-Fi password from all my Apple devices?
No, deleting a network on your MacBook Air will only affect that specific computer. However, if you have iCloud Keychain enabled, the password may also be removed from other devices synced with that Apple ID, as the system will assume you no longer want to use that network.
Is it possible to restore a deleted network without entering a password?
No, after you choose "Forget this network," the password is permanently deleted from the device's memory. You'll need to re-enter the password to reconnect. If you don't remember it, you'll have to look it up in the router settings or on another device where it's stored.
Why doesn't my MacBook Air see the network after uninstalling?
If you've deleted a network but it doesn't appear in the list of available connections, your router may be hiding its SSID (a hidden network). In this case, select "Other Network" in the Wi-Fi menu and enter the name and password manually. Also, check that the Wi-Fi module itself is enabled.
Does deleting a network affect internet speed?
Removing a network by itself won't speed up your internet. However, if your laptop stops trying to connect to a weak or congested signal it previously remembered, this can improve connection stability and force the device to switch to a better signal source.
